Meet the Wren – Write Off: the infinitely refillable pen that gives disposable pens another life. An estimated 9 billion disposable pens are thrown away globally each year. It’s a staggering number. Having spent years creating pens designed to be reused for a lifetime, I couldn't help but feel for these poor little pens – destined to be buried for millennia. It was time to close the loop – to find a way to repurpose them and give them a brand-new life.

Enter the Wren – Write Off, my boldest project to date. Over the past year, we've been working with schools and organisations to intercept stationery waste at the source, preventing it from reaching landfill. This precious plastic is then meticulously separated and sorted to create the wonderful colours you see before you.

Crafted in collaboration with the brilliant Brothers Make, each lid is made by chipping, injection-moulding and hand-finishing the reclaimed plastic – a process that’s more artisan than assembly line. This unique method means every lid is completely one-of-a-kind.

This isn’t just a pen – it’s a small act of rebellion against waste, and a celebration of creativity.

Included in the box:

  • The Wren – Write Off in your choice of colours
  • Japanese-made Writing Tip*
  • 3ml Midnight Ink sample
  • Ink Reservoir

*0.3–0.5 depending on pressure

Specifications:

  • Length capped – 80mm
  • Posted (cap on the end of the pen) – 120mm
  • Pen barrel diameter – 13mm
  • Weight – 14g

Full FAQs and a video guide to getting started with your Wren can be found here.

What ink can I use?

The Wren is compatible with all but the most experimental fountain pen inks (think shimmer + iridescent). We offer a beautiful range of ink for fountain pens, which are perfect for the Wren and can be found here.

Note: Calligraphy Ink has an acrylic binder which will block the pen and is not suitable for use with the Wren.

Some ink colours can concentrate in the tip, so you may experience a lighter colour after a line or two. This is completely normal and looks quite nice!

How do I store the reservoir and tips?
You can store reservoirs and tips, and change to a different colour using spare reservoirs and my reservoir storage containers.

How long will the tips/ink last?
You can expect the high-quality, Japanese-made tip to last for months of use. We tested a single ink fill in the Wren on a plotter – a device used for precision drawing – and it wrote consistently for 344 metres. That's the equivalent of 50 A4 pages of handwriting!

When the tip eventually dulls, you can find packs of three replacement tips here.

Anything else I should know?
Yes! Each lid is completely unique, made using a one-of-a-kind blend of upcycled plastics. That means colour density and placement will vary from pen to pen. Some are bold and bright, others more subtle – it’s all part of the charm. Think of it as a lucky dip for your desk. No two lids will ever be the same.

Here’s the how (and why)

Waste Plastic: Reimagined

Every year, billions of plastic pens are thrown away – we wanted to do things differently. By collecting waste from local schools and organisations, we’ve reimagined what a pen can be: thoughtfully made, built to last, and crafted with care from reclaimed plastic.

Giving waste a second chance

We partner with local schools and organisations to collect used plastic pens and markers – saving them from landfill and starting their journey toward something better.

Prepped with care

In their workshop, the incredible team at Brothers Make meticulously sort, wash, and chip the plastic into colourful flakes – ready for transformation.

Small batch, big impact

Each pen lid is injection moulded, creating one-of-a-kind pieces. Every lid is then finished by hand – it's small batch production done right.

My wife absolutely loves the pen. Two colour mix and deep black ink. Easy to fill, compact and writes fluidly.

Beautiful pen

Absolutely love my wren! Already looking at getting another colour!
Nice small size to carry round but then opening to full size pen - glides across the paper

This pen just glides across the pages. My hand writing is... Awful , to say the least, but the beautiful action of this pen helps me to make writing a pleasure.
